ABSTRACT:
This invention provides a circuit, which performs a high quality mapping operation by giving a perspective transformation effect to a mapping data of a rendering polygon. The circuit has a mechanism to divide edges and mapping data of a figure in a display and calculate a virtual mapping address, a pixel generator to generate a pixel data for pixels inside of the displayed figure and a virtual mapping address of the pixel data, a virtual address converter to convert the virtual mapping address to a mapping address, and a mapping memory to store the mapping data.
